H A Dtag_matching.rst14 The ordering rules require that when more than one pair of send and receive
16 and the earliest posted-receive is the pair that must be used to satisfy the
23 corresponding matching receive is posted. If a matching receive is posted,
44 There are two types of matching objects used, the posted receive list and the
45 unexpected message list. The application posts receive buffers through calls
46 to the MPI receive routines in the posted receive list and posts send messages
47 using the MPI send routines. The head of the posted receive list may be
50 When send is initiated and arrives at the receive side, if there is no
51 pre-posted receive for this arriving message, it is passed to the software and
54 specified receive buffer. This allows overlapping receive-side MPI tag
